If you wish to work on this issue as part of the Hackathon and be eligible for prizes, please create your merge requests between Feb 22, 2022 and Feb 24, 2022.
The work for this issue should involve only what's listed in the previous section. If you identify other work that needs to be done, create separate, unlinked MRs as needed to address those items.
When using automated test results for identified work, use this issue to work only on the listed lines. For example, if the tests list several lines that show the word "admin" as needing to possibly be "administrator," do not modify other parts of the page that may also include "admin," as the testing may have excluded those lines (for example, they may be part of the Admin Area of GitLab).
